Abstract
A rotary internal combustion engine includes a fuel intake port located in the periphery of the rotor housing near the air inlet end of the major axis of the two-lobed profile defined thereby. A rotary valve controls communication between the fuel intake port and a source of gaseous fuel such as natural gas. The valve includes a rotary valve member so that the communication is open between the source and the fuel intake port when rotor pockets are facing the intake port.
